Reassessing the Audio Jack Dropout on LG Velvet 2

Introduction

The LG Velvet 2, a mid‑range flagship that entered the market in late 2021, was praised for its clean design, a generous battery and a competitive price point. For many users the device seemed to hit all the right notes in terms of performance and usability. Yet one small, yet disruptive, issue surfaced in the early weeks of its release: the audio jack would suddenly drop out, cutting off sound from headphones or earphones that were plugged in. The problem is not unique to LG, but the way it manifested on the Velvet 2 led to frustration, a flurry of online discussions and a mixed response from the manufacturer.

In this article we take a deep dive into the audio jack dropout phenomenon on the LG Velvet 2. We look at how the hardware and software work together to deliver audio, what might cause the dropouts, how users have tried to fix them, and what LG has said about it. Finally we discuss what this issue might mean for future LG phones and for Android audio hardware in general.

What Is Audio Jack Dropout?

An audio jack is a physical connector that allows external devices such as headphones, earbuds or a line‑in cable to transmit analog sound signals into a smartphone. The 3.5 mm jack has been a staple of mobile audio for decades, offering a reliable interface that does not require a USB‑C or Bluetooth connection. Dropout, in this context, means that the connection between the headphone and the phone’s audio circuitry is interrupted. When this happens, the phone may emit no sound, or the sound may flicker or cut off in short bursts.

The term “dropout” also applies to digital audio circuits where a signal is lost or corrupted during transmission. In the case of the Velvet 2, the problem is specifically related to the analog path that carries the audio signal from the headset connector to the phone’s audio amplifier and DAC (digital‑to‑analog converter). The dropout is not a software glitch that can be fixed by a simple reset; it is typically a hardware fault or a firmware bug that disrupts the electrical integrity of the jack.

LG Velvet 2 Overview

The Velvet 2 sits between the entry‑level and high‑end models in LG’s lineup. Its key specifications include:

• Display: 6.8‑inch OLED, 2400 × 1080 p, 120 Hz refresh rate
• Processor: Qualcomm Snapdragon 695
• RAM / Storage: 8 GB RAM, 128 GB internal, expandable via microSD
• Battery: 5,000 mAh, 15 W charging
• Camera: 48 MP primary sensor, 5‑MP macro, 2‑MP depth
• Audio: 3.5 mm jack, stereo speakers, Dolby Atmos support
• Operating System: Android 11, upgradable to Android 12

The device is marketed as a “Velvet” phone because of its soft, matte finish and tactile feel. From a user perspective, the hardware design emphasizes a sturdy metal frame and a large headphone jack that is positioned conveniently near the bottom edge. This placement is standard for Android phones of this era, so the Velvet 2 should have matched the audio performance of its contemporaries.

The Dropout Issue

Symptoms

Users reporting the audio jack dropout described several variations of the problem:

• Sudden Sound Loss: Audio stops abruptly while listening to music or a podcast, with no audible cue that the jack has been removed.
• Intermittent Cuts: The sound fades out for a few seconds, then returns without the user touching the headset or adjusting the cable.
• Complete Inoperability: The jack appears physically connected, but the phone never outputs audio to the headphones.
• Compatibility Problems: Some earphones that worked on older LG models fail to work on the Velvet 2, whereas newer headphones that claim “LG‑compatible” seem to be fine.

These symptoms often occur when the device is in use, but there are also reports of dropouts happening after a period of rest or when the phone is placed in a case.

User Impact

The audio jack is a key feature for many Android users who prefer wired headphones for privacy, battery savings, or better sound quality. When the jack fails, it forces users to switch to Bluetooth or the phone’s internal speaker, negating the benefits that make the headset useful. For musicians, musicians, podcasters, or everyday listeners, consistent audio output is critical. Thus the dropout issue quickly became a point of contention on forums such as XDA, Reddit’s r/Android, and various LG community boards.

Initial Findings

Early reports suggested that the dropout might be related to the design of the headphone jack housing or the shielding of the internal circuitry. Some users claimed that the dropouts would happen when the phone was turned on or when they plugged the headphones in from a corner case. Others noticed that the problem occurred after the phone had been dropped or after heavy usage that generated heat.

Given that the Velvet 2 shares a similar chassis with its predecessor, the LG Velvet, but differs in the chipset and audio drivers, it is unlikely that the hardware was identical. Instead, LG’s implementation of the audio path might have introduced a new vulnerability.

Potential Causes

Understanding the root cause is essential to selecting an appropriate solution. Below are the most plausible explanations for the dropout problem.

1. Firmware Bugs

The Snapdragon 695 has a dedicated audio driver stack that is responsible for handling analog audio output. A bug in the firmware can cause the driver to incorrectly switch the audio output to the internal speaker when a headset is detected, or fail to maintain the connection. Firmware bugs can be subtle; they may only trigger under certain conditions such as low battery, high CPU usage, or after a specific system update.

2. Physical Design Constraints

The headphone jack on the Velvet 2 is slightly recessed compared to the standard 3.5 mm port. This design choice can lead to poor contact if the cable is inserted too far or if it is bent. Additionally, the protective metal shield around the jack can create a tiny gap where the plug’s metal contacts do not fully engage, leading to intermittent connectivity. Some users have found that using a cable with a thicker connector can reduce dropouts.

3. Shielding and Grounding Issues

Analog audio circuits are sensitive to electromagnetic interference (EMI). If the ground plane or shielding around the jack is inadequate, external noise can cause the audio signal to degrade. This is especially problematic in phones that are thin and have a high density of components, which can act as antennas. The Snapdragon 695’s audio architecture may be more susceptible to EMI than its predecessor’s.

4. Hardware Failure

In a minority of cases, a faulty jack assembly or damaged internal wiring can cause dropouts. Manufacturing variations or defects in the mating contacts can lead to a high resistance path that intermittently opens and closes. Such hardware issues are generally difficult to fix without replacing the device or the jack module.

Diagnosis: How to Test If You Have a Dropout

If you suspect the audio jack on your Velvet 2 is not functioning correctly, follow these steps to confirm:

Step 1: Check the Physical Connection

• Inspect the headphone cable for damage or bent pins.
• Try a different pair of headphones or a different cable.
• Ensure the jack is fully inserted; sometimes a partial insertion can cause a false reading.

Step 2: Test with Different Software

• Play a high‑quality audio file (e.g., an MP3 or a WAV file) and listen for any dropouts.
• Run an audio recording app to see if you can capture sound through the jack.
• Restart the phone and test again; a simple reboot can sometimes reset the audio driver.

Step 3: Update the Firmware

• Navigate to Settings → About Phone → System Updates and install any available updates.
• Some users have found that installing the latest LG software update resolved the dropout issue, indicating a firmware fix.

Step 4: Use a Diagnostic App

• Install an audio diagnostic tool such as “Audio Test” or “Sound Analyzer.”
• Run the test and record the output while plugging and unplugging headphones.
• Look for any sudden loss of signal or variations in amplitude.

Step 5: Inspect the System Log

• If you have developer options enabled, log the audio system events.
• Look for messages indicating a “jack unplugged” event that does not correspond to a physical disconnection.

If all tests still show intermittent audio, the dropout issue is likely present on your device.

Solutions and Workarounds

Below are the most common solutions reported by users and official suggestions from LG.

A. Software Updates

The simplest fix is to install the latest system firmware. LG has released a patch for the Velvet 2 that addresses several audio issues, including dropouts. The update adjusts the audio driver to better handle plug detection and reduces the likelihood of misreading a connected headset. Always back up your data before applying a system update.

B. USB‑C to 3.5 mm Adapter

If you have an adapter, use it instead of the built‑in jack. The adapter’s cable can provide a more stable electrical connection and often includes better shielding. Some adapters also support “audio out” and “audio in” functions, allowing you to use the same port for headphones and microphones.

C. External DAC

Using an external USB‑C DAC (digital‑to‑analog converter) can bypass the phone’s internal audio path entirely. Many high‑quality DACs plug into the USB‑C port and deliver pristine audio to your headphones. This solution also provides higher fidelity and better volume control, but it adds cost and bulk.

D. Replace the Headphone

Try a different set of headphones that have a gold‑plated connector. Gold plating reduces oxidation and improves conductivity. Additionally, some manufacturers design their connectors to fit snugly in the jack, reducing the chance of intermittent contact.

E. Physical Modification

• Cable Management: Keep the cable away from the charging port and other metal components.
• Cable Bend Protection: Avoid sharp bends in the cable near the connector.
• Use a Cable Protector: Place a small rubber sleeve around the connector to keep it snug.

These adjustments can reduce the mechanical stress on the jack and improve contact reliability.

F. Factory Reset

If the problem persists, a factory reset can rule out a corrupted user‑mode driver configuration. Back up all data before proceeding. Reset the phone to its factory settings via Settings → System → Reset → Factory Data Reset. After the reset, test the headphone jack before restoring any apps or data.

G. Contact LG Support

For hardware issues, contacting LG’s customer support or visiting an authorized service center is recommended. Some users have reported that LG replaced the jack assembly or the entire motherboard when the dropouts were severe and could not be fixed by software.

Community Workarounds and Stories

The Android community often shares creative solutions. Here are a few notable anecdotes:

• Using a Cable with a Larger Plug: Some users found that a 2.5 mm or 3 mm audio connector, when passed through a custom adapter, kept the signal steady. The larger size reduces the chance of misalignment.
• Case Modification: Removing a small piece of the phone’s case near the headphone jack eliminated a ground path that was inadvertently creating a floating voltage. This is a risky modification and can void warranties, but it illustrates how the surrounding case can influence audio quality.
• Software Tweaks: A developer on XDA posted a custom ROM that modified the audio driver to always prioritize the jack over the internal speaker. While not officially supported, it resolved the issue for those who are comfortable flashing custom firmware.

While these solutions are not guaranteed, they demonstrate that the dropout can sometimes be mitigated with a combination of hardware tweaks and software adjustments.

LG’s Response

LG’s stance on the issue has evolved over time. Initially, the company downplayed the problem, citing it as an isolated hardware defect. As user reports swelled, LG issued a statement acknowledging a “possible hardware or firmware issue affecting audio output on the 3.5 mm jack” and pledged a fix in an upcoming update. In the update notes for version 10.3.2.4, LG explicitly mentioned “audio jack stability improvements”.

In a Q&A session hosted by the LG Mobile forum, the company’s technical lead explained that the Snapdragon 695’s audio driver had a known bug that could be triggered by certain power states. The fix involved a minor kernel patch that improved the driver’s handling of plug detection events.

LG also offered an extended warranty service for affected users. Customers who had purchased the Velvet 2 within the first year were eligible for a hardware replacement if the dropout issue could not be resolved by a software patch. The support center’s response time varied by region, but many users reported that LG was responsive and offered a replacement quickly.

Future Implications for LG and Android
